IMPROVEMENT IN SAD-IRONS.

th s tlntule rennet it in flgrst itttters new mu mating putt at tip withKNOW ALL MEN BY THESE PRESENTS:

That I, Jonson W. HALL, of the city and county of Worcester, andCommonwealth of Massachusetts, have invented certain new and usefulImprovements in Sad-Irons; and I do hereby declare that the following isa full, clear, andexact description of the same, reference being had tothe accompanying drawings, forming a part of this specification, and inwhich- Figure 1 represents a perspective view of my improved sad-iron asit appears when placed upon its heating-stand. 1 a

Figure 2 represents a section on line m z, fig. 1; and

Figure 3 represents a section of a portion of the sad-iron and stand online y y, fig. 1.

To enable those skilled in the art to whieh'my invention belongs to makeand use the same, I will proceed to describe it more in detail.

In the drawings, the part-marked A represents my improved sad-iron inposition upon the heating-stand B, the latter being made of sufficientsize to support two sad-irons at a time. In the top of the stand B aretwo holes, 0 C, while upon each side. of each hole 0 projects a conicalpoint, a. A is the handle by which the iron is used.

Stand B is supported by legs D D. The body of'the sad;iron A is madehollow, or with a chamber, E, and is open both in rear and front, asshown in the drawings. The rear opening is made to correspond with theopening in the stand 13, as shown at I), while the front opening isthrough the chimney F, to theend of which is hinged the valve 0. Anopening, (Z, is made in the rear upper side of the sad-iron, and coveredwith an isinglass window, e. In this instance the window of isinglass isfitted into the inside of a flange, f, which answers as a frame, theglass being held in by plaster of Paris. 7

In practice, it may be found more convenient to have two flanges indove-tail shape, between which the isinglass can be slipped, aperforated plate being slipped in over the glass, if found necessary, toretainit in place;

The object of the window is to enable the ironer to see the lamp-flame,so that it may be regulated to burn with the proper clearness, mysad-iron being designed so as to enable a kerosene-lamp to be used forthe pur- -pose of heating the same.

The lamp should be supported so that the flame will be quite or entirelyabove the top of the stand B.

It will be observed that the lower inner surface, G, of' the sad-ironinclines up toward the back, H, as it approaches the point I, and, as aconsequence, the flame and heated air and gases from the lamp impingemore eliectually against that part of the iron where the heat isrequired.

By the employment of the chimney F, a suthcient protection and-draughtare secured to burn kerosene-oil very perfectly, for the purpose ofheating thciron.. g

The valve 0, when the iron is placed on end for heating, falls back andleaves the chimney F open, while, when the flat or iron is removed andplaced upon a table for use, the valve 0 falls and closes the top ofchimney F, thus preventing a draught of cold air through the iron whileitis in use.

If the chimney F were left open during the operation of ironing, thecurrent of cold air, which would pass through chamber E, would tend tocool the flat or iron very much, and to such a degree as to require arepe= tition of-the heating operation much more frequently than whenthevalve c is used. Valve 0, it will be observed, is automatic in itsoperation.

The rear of the iron is provided with two conical holes, in an, intowhich the projections a a fit when the fiat is placed in position forheating, as shown in the drawings, thus insuring the proper position ofthe iron upon the heating-stand. I i

I prefer to use a lamp with double tubes and wicks, thereby heating twoflats or irons from the same lamp at the same time.

Having described my improvements in sad-irons, what I claim therein asnew and of my invention, and desire to secure by Letters Patent, is-I 1. The combination, with the rear of the iron, of the concavities m m,foithe purposes stated. 2. The combination, with the year of the iron,of window a, substantially as and for the purposes set forth- JUDSON W.HALL.
